The D-Tap Cable (also known as P-Tap) is designed for an alternative way to power the P360/P200/P180E. A 2.5mm DC Connector plugs into the light, the opposite end features an industry standard D-Tap Connection that plugs into professional DC Broadcast Batteries. This is a coiled cable that extends to 2 ft long and allows for direct connection to a DC battery without having excess slack on set.
